Abstract

A transcatheter insertion system for the insertion of an intracorporeal device using an insertion device, wherein the system includes an outer sheath arranged and configured to form a passageway for the intracorporeal device and/or the insertion device and the outer sheath includes for guiding the insertion device. The present disclosure also relates to an outer sheath and an insertion device for use with the system.

Claims

exact text as granted — not AI-modified
1 .- 27 . (canceled) 
     
     
         28 . A method for the transcatheter insertion of an intracorporeal device into a patient, comprising:
 (a) puncturing at least one anatomical wall separating anatomical compartments;   (b) delivering the intracorporeal device into the patient; and   (c) implanting the intracorporeal device through the anatomical wall(s);   wherein steps (a), (b) and (c) are carried out using a transcatheter insertion system comprising an insertion device and an outer sheath arranged and configured to form a passageway for the intracorporeal device and/or the insertion device and said outer sheath comprises means for guiding the insertion device.   
     
     
         29 . The method according to  claim 28 , comprising the step of guiding the insertion device using said outer sheath arranged and configured to provide a passageway for the intracorporeal device and/or the means for guiding the insertion device. 
     
     
         30 . The method of  claim 29 , wherein the guiding means is positioned adjacent to or at a distal end of the outer sheath. 
     
     
         31 . The method of  claim 29 , wherein the guiding means is substantially ring-shaped. 
     
     
         32 . The method according to  claim 29 , wherein the inner dimensions of the guiding means is smaller than the inner dimensions of the outer sheath. 
     
     
         33 . The method according to  claim 29 , wherein the guiding means comprises a substantially rigid material. 
     
     
         34 . The method according to  claim 29 , wherein the guiding means comprises an inflatable balloon. 
     
     
         35 . The method according to  claim 28 , further comprising the step of detecting and/or visualising the transcatheter insertion system. 
     
     
         36 . The method according to  claim 35 , wherein the step of detecting and/or visualising comprises the use of a marker provided on a guiding means, a delivery sheath, an outer sheath, a dilator and/or a guide wire. 
     
     
         37 . The method according to  claim 34 , wherein the step of detecting and/or visualising is carried out using X-ray, fluoroscopy, echocardiography and/or ultrasound techniques. 
     
     
         38 . The method according to  claim 28 , wherein steps (a), (b) and (c) are carried out using an all-in-one insertion device. 
     
     
         39 . The method according to  claim 38 , wherein the all-in-one insertion device comprises a guide wire, a dilator and a delivery sheath. 
     
     
         40 . The method according to  claim 28 , wherein the insertion device comprises a guide wire which comprises an integrally formed puncture head. 
     
     
         41 . The method according to  claim 28 , wherein the insertion device comprises a dilator which is slidable relative to a guide wire. 
     
     
         42 . The method according to  claim 28 , wherein the insertion device comprises a delivery sheath which is slidable relative to a guide wire. 
     
     
         43 . The method according to  claim 28 , wherein the insertion device comprises a guide wire, a dilator and a delivery sheath which are movable relative to each other. 
     
     
         44 . The method according to  claim 28 , further comprising the step of pressing the outer and/or delivery sheath against the anatomical walls to facilitate puncture and provide support to the anatomical walls. 
     
     
         45 . The method according to  claim 28 , further comprising the step of dilating a puncture after step (a). 
     
     
         46 . The method according to  claim 28 , comprising the step of steering the outer sheath, a delivery sheath, a dilator and/or a guide wire using a steering means. 
     
     
         47 . The method according to  claim 46 , wherein the steering means comprises one or more curved portions on the outer sheath, delivery sheath, dilator and/or guide wire. 
     
     
         48 . The method according to  claim 46 , wherein the steering means comprises a proximal handle. 
     
     
         49 . The method according to  claim 48 , wherein the steering handle comprises a rotation knob. 
     
     
         50 . The method according to  claim 28 , comprising the step of securing the intracorporeal device to a distal end of the insertion device prior to and/or during step (b). 
     
     
         51 . The method according to  claim 28 , comprising the step of detaching the intracorporeal device from the insertion device following step (c). 
     
     
         52 . The method according to  claim 50 , comprising the use of one or more retractable tabs. 
     
     
         53 . The method according to  claim 28 , wherein the intracorporeal device comprises a connector and/or a flow regulator device.
